  • Let's use it!

    Native design. The 68uH closed core inductor. True Low ESR, high RMS in/out capacitors.
    There is even no place for feedforward capacitor on so large board. Feedforward capacitor 33nF-220pF you must choose yourself depend on Output Voltage and solder it directly at the variable resistor manually (see datasheet LM2596). It should be better if the board has additional soldering pins specially for feedforward capacitor package 0805 or 1206. Some other low price DC-DC converters provide less quality inductor, lower value capacitors and narrow PCB tracks.
    Work's well. Let's use it!
  • Converter for use to make a "line-out" output when there's only s

    posted by idosensei

    Very easy to use. Very useful.Used when you want to connect an amplifier to a radio that has no output. You connect this gadget to the wires going out to the speakers, and you get a plug (RCA) that's just like any other "line out" -- good to go for using to connect an amplifier.
    Easy to install. Strip wires going to speakers, connect wires coming from gadget - one to each speaker wire, re-insulate, and you're good to go!Installing this unit does require some knowledge of electronics.
    Good price.Useful for connecting amplifier to existing sound system that has no "line out".Installation requires some knowledge.
  • Works as advertised

    posted by fryslan76

    No nonsense unit, just two wires to connect and an USB port on the business end. The unit is small and comes with two nice fixing point to attach it where ever you want.
    I could be handy if the input wires where a bit longer but that is not a con, only for ease of installement.The casing is plastic so sticky tape will hold it in place but I do not know how it will cope with heat.So far I only tested it to charge a cell phone for a while and it did not get hot.
    Works as advertised, very slim unit so easy to place some where. And realy a no brainer to install.
  • Switching Regulator

    posted by Logsplitter

    A simple device, no external components required. Output ripple is very low, as is heat as full output. No heatsink necessary even at continuous full output, (with 15 volts supply voltage).
    The regulators can be combined with steering diodes to increase output current. The ripple does not appear to increase even when combining the output of 3 regulators.
    An excellent stand alone regulator, especially for a USB power source. Have used more than a dozen for automotive cellphone chargers without a single failure
  • Great boost converter with stable power

    posted by bear123

    - stable voltage- effiecency is very good- able to boost variably and accurately - fuse- green power LED
    - I modded mine with sku 187376 (mini voltage meter V20D) on the output so I can see the voltage at all times under load. This is an easy mod and well worth the time spent. - I tested this boost convertor with 10 x 1.2v NIMH AA batteries running at 12v and I was able to get a maximum stable output of 26.2v at 76 watts or 2.9 amps. This is very good results for rechargeable NIMH AA battery power source. I will test next with some larger DC input power source and I will assume I will be able to boost to higher stable voltage but not exceeding the input output specs of this boost converter. Seems very efficient and provides smooth adjustable power. You can adjust the output as fine as 2 decimal places easily. What I mean is the adjustment provides fine tuning so I can dial in lets say 15.24v or 28.15v exactly as a random example. Once under load depending on the input power source the voltage will likely drop a little or a lot which is expected.
    Seems to be a great quality boost converter so far. Its small and did not create much heat with an output of 26.2v at 76w for about 5 min. I would think the 150w rating is fair for maximum spec for this unit. I would not advise exceeding this.
